Abstract: 1311585 Tyre pressure indicating devices BENDIX CORP 2 July 1971 [14 Sept 1970] 31129/71 Heading B7C [Also in Division G1] A vehicle wheel and tyre assembly tyre pressure indicating arrangement, carried by a vehicle, comprises: a transmitter means 22, carried by the vehicle, for transmitting a radio frequency signal; a passive transponding means 14, e.g. an L.C. circuit 28 whose resonant frequency is varied in response to the tyre pressure, carried by the assembly and adapted to transpond a radio frequency signal in response to the transmitter means signal; sensor means causing a variation in the transponding activity of the transponding means 14 in response to the tyre pressure, e.g. an aneroid capsule varying either the inductance or capacitance of the L.C. circuit 28 in response to the tyre pressure; and indicator means comprising a receiver 24 and display 18 which receive the transponded signals and indicate a variation in the tyre pressure. The transmitting means may sweep a frequency range corresponding to the frequency range in which the resonant frequency of the L.C. circuit lies, the exact value of the resonant frequency being dependent upon the tyre pressure, and the frequency of the transponded signal being representative of the tyre pressure which is then indicated by the display 18. In a further embodiment the transmitting means transmits a pulsed radio frequency signal 26 which causes the L.C. circuit 28 to resonate only if a switch 30 is closed, the switch 30 being operated by a diaphragm (52),Fig. 4 (not shown), and only closing if the tyre pressure drops below a predetermined limit, and transpond a signal which is received by the receiver 24 and the display 18 then indicates the drop in tyre pressure.

The shafts 18, 14 are geared by wheels 19, 20 arranged centrally between the cranks 21, 22. The shaft 18 may be above, below, or in the same horizontal plane with the shaft 14. The shaft 18 is slid endwise into position with anti-friction bearings 27. The webs 24.. 26 have aligned apertures graduated in size. The webs 24, 25 have seating-members 29, 30; the webs 23, 26 carry cover plates 31, 32. A separate oil sump 33 is arranged beneath the casing. The sump 33 and the adjacent part of the casing form halves of the axle bearings. The sump has three wells 36.. 38, and the wells 36, 38 have oil-withdrawal pipes 39, 40 which are connected with eccentric-operated feed pumps 41. The wheel 20 dips into the well 37. The piston-rods pass through glands to cross-heads which carry scraper rings 50. The cross-head spaces are closed and connected by an interconnection 49. Tubes 52 containing non-return valves 53 and a pipe 54 are provided to detect steam or oil leakage past the stuffing- box into the cross-head guides. The valvechests have spaced liners 57, 58 and house waisted piston valves 59. The liners beyond the chests house waisted cross-heads 61 and carry conical shields 60 and drain pipes 62. A modified form of Hackworth gear operates the valves. A horizontal link 63 extends from the cross-head 61 to a vertically-disposed link 64 the upper end of which is rotated by a crank-pin 65 on a shaft 66 supported in bearings carried by the webs 24, 25. The lower end of the link 64 is pivoted to a block 68 slidable in an arcuate guideway 69 mounted in a shell angularly adjusted by a lever 71 connected to the reversing-gear. The primary valve-gear parts are enclosed within the casing and a cover 74 is secured thereto. The shaft 66 is driven by toothed gearing from the main shaft. The casing contains caps to facilitate machining of the crank-case and a bearing-cap for the sleeve carrying the shaft 66. The crank-case has a large cover 86 to permit the insertion of the assembled shaft. Drainage valves 80, opened when the lever 71 is in mid-position, are connected to conduits 82 which lead to a low level in the engine exhaust. One or more engines may drive a locomotive.

Abstract: 1372670 Read-write amplifiers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 July 1973 [8 July 1972] 31985/73 Heading H3T A small signal amplifier suitable for the writein or read-out of information from a memory cell comprises first and second inverters I 1 , I 2  including IGFETs 1-4, a first switch 5 providing negative feedback between the output and input of the first inverter I 1  during the first period of a cycle, a second switch 6 providing positive feedback between the output of the second inverter and the input of the first inverter during a third and final period of the cycle with the input signal being applied during the intermediate second period of the cycle. In operation, during the first period when switch 5 is closed a charge corresponding to a threshold voltage level is stored in the gate-source capacitance of FET 1 setting the amplifier in an unstable equilibrium. During the second period, the presence of an input signal at S provides an additional charge and when switch 6 is closed during the third period, the charge level present at the gate of 1 is already present in an amplified form at output Q and is fed-back to the input gate of 1 so that depending on the input signal the circuit switches to one or other of the two stable states from the unstable state of equilibrium. A negative feed-back between theoutput and input of inverter I 2  during the first period may be provided via switch 6 or via a third switch (not shown). To reduce power dissipation, the supply voltages may be switched off between the end of the first period and prior to the commencement of the third period.

Title: Improvements in methods of and apparatus for generating and controlling positive ioncurrents
IPC: H01J19/68
Filed: 1923-12-21
Abstract: 208,728. British Thomson-Houston Co., Ltd., (Assignees of Kingdon, K. H., and Langmuir, I.). Dec. 21, 1922, [Convention date]. Vacuum or low-pressure apparatus, arrangements of.-Positive ions are produced in a discharge tube. independently of ionization by colli. sion, by bringing into contact with a positively charged electrode a vapour, preferably of an alkali metal such as caesium or rubidium, having a lower electron affinity than the electrode, which is heated above a critical temperature, such as 1000‹ C., at which ions are generated. The current through the tube may be carried wholly by the passage of ions to a negatively charged cathode, or the ionic emission may be used for neutralizing the space charge of an electron discharge. The pressure in the bulb should be below that at which appreciable ionization by collision occurs, and when caesium is used, a pressure below onetenth of a micron of mercury is preferred. The bulb is highly exhausted and caesium is admitted from a reduction tube containing a mixture of caesium chloride with a reducing agent such as magnesium or calcium in excess. A film of caesium is thereby formed on the ionizing electrode which is pneferably of tungsten, nickel, or molybdenum. In the rectifier shown in Fig. 5 an electron emitting cathode 43 is surrounded by an ionizing anode 42 of cylindrical form and corrugated. The anode is heated by radiation from the cathode or by high frequency currents induced by a winding 55 around the tube. The length of the paths of the ions emitted from the anode is increased owing to the corrugations, and a greater neutralizing effect is obtained with a resultant increase in the current through the tube. Positively charged plates are mounted at the ends of the anode to prevent the escape of ions. The anode and cathode are connected through a load 53 and the secondary 52 of a transformer.
